I'm sorry to say this :
The more updates, the less I like playing because it becomes less controllable.
It makes me mad.
I feel the biggest problem is, you know, the physics.
I've read a note somewhere we should stop talking about this, but I will get back to it.
I think everytime you update the game, you make regressions around physx : You make a odd / weak steering waiting system, you add blocks everywhere, you change the terrain, you change the friction ... But you must first correct the physx, otherwise you will never end losing time doing regressions.
I don't think you don't do anything against that or you don't know how to correct this problem, but I've found something on the physx documentation that can open your eyes and help you a little bit : http://docs.nvidia.com/gameworks/conten ... anced.html
This is however a basic article that is still interesting : http://gamedevelopment.tutsplus.com/art ... -cms-21418
I'm sorry if you feel I show disrespect, this is not my goal. Maybe you could be more transparent about the problems you have and the updates you make, so we, as testers, will be able to help you more efficiently, not only by telling you what is bad but also how you can correct - before adding anything.
Have a great day.
